How to choose a welding helmet among a variety of designs? Welders, people with practical talents of inventors, so many people make it themselves. Even the best samples and popular models may not satisfy the scrupulous requirements of welders. The best manufacturers understand what to look for in order to increase the popularity of their models. The article is intended to sanctify which welding mask is better, which company is better, the functionality and cost of popular products.

At this time, there are 4 main types of welding masks.
The welding shield is the simplest type of mask, but it has a significant drawback. It takes one hand to hold it in front of the face. This creates an inconvenience, and in many cases leads to the impossibility of using it.
Therefore, they use a traditional mask with a mechanism for raising and lowering the shield. The front part, which is a shield, is raised and fixed by a temporary hold over the head, so that by moving the head the mask returns to working condition. Despite the fact that such a mask has acquired the widest use, it is not free from a large number of inconveniences and disadvantages. Firstly, the "nod" of the head to return the mask to the state of protection disturbs the concentration of attention on the subject of work. Secondly, in hard-to-reach places and in non-standard positions, this type of mask may not be possible.
There are also masks with lifting light filters, the advantage of which is not only the ability to use in hard-to-reach places, but also the presence of a permanent transparent window that protects against ultraviolet and infrared radiation.
There are welding masks, supplemented by air filtration, to protect the respiratory system from harmful gases and poisoning.
Recently, the most popular is the chameleon-type mask. The advantage of this type of mask is the presence of a special electric light filter. Which contains a liquid crystal layer with polarizing films that lose transparency when a control current passes through them. To increase the quality of dimming in more expensive devices, several layers of LCD are used.
The last, recently emerged species - "chameleon" will be considered in detail. It has the most widespread use and can vary greatly in performance, usability and design.
Chameleon masks take less than 1 millisecond from flash light to blackout.Since the molasses of the welding arc has different brightness, it is very convenient to use filters with adjustable shade. And so, as welding work can be carried out both in areas well-lit by the sun's rays, and in closed rooms with poor lighting. It is appropriate to adjust the initial dimming.
This adjustment allows you to adjust the amount of shading so that the subject is clearly visible. An increase in dimming is often necessary when working with constant bright sunlight or artificial lighting.
This is the time after which the filter actually lightens after the end of the welding arc. Adjustment is sometimes necessary when welding various types of metals. Ferrous metals cool down quickly and the delay time can be set to a minimum. But when welding cast iron, stainless steel and non-ferrous metals, the brightness at the welding site can last up to 1 second, and an earlier shutdown of the light filter can cause damage to the eyes.
This adjustment allows you to adjust the threshold for the filter. This is necessary for various types of welding work.
Welding helmets of branded manufacturers are made taking into account the above points. But some have one significant drawback. They are equipped with non-removable power supplies that do not have switches. On the one hand, this is reliable operation due to the absence of terminal oxidation. On the other hand, when the battery is discharged, replacing it is difficult, and sometimes impossible. The microcircuits on the electronic board may need firmware.
Most often, battery discharge occurs due to a violation of the operating conditions of the device. In cases of low temperatures, the current consumption in idle mode increases sharply. At elevated temperatures, the quiescent current of shunting electrolytic capacitors increases, which even leads to their failure, or the earliest discharge of the battery.
High humidity can cause leakage between the conductors of the board micromounting, electrolysis with mechanical destruction of electronic parts and not only discharge the battery, but also complete failure of the electronic unit. Therefore, the operating conditions must not only be read at the time of purchase, as characteristics, but also observed as the conditions for the safety of the device.
The rating of high-quality welding masks is presented by both foreign manufacturers and domestic ones. Also, inexpensive and high-quality goods are presented by Chinese manufacturers. Considering the main characteristics of welding helmets, you can use various criteria for choosing the required product.
This mask is from a German manufacturer, Fubag company, founded in 1973. Since 1996 it has been known on the Russian market.
